Abstract:
In this paper, the content of moisture, ethanol-soluble extractives, total saponins and polysaccharide of different tuber samples of Hemsleya zhejiangensis, from different localities, years and seasons, were detected based upon Chinese Pharmacopoeia 2010 version. The samples of roots, stems and leaves in summer were detected as well. The results are mainly as follows. (1)With tuber quality increasing, the content of total saponins increased and then decreased. The individual quality of tubers getting 594.06 g, the content of total saponins reached the peak. (2) The content of active ingredients in different localities was significantly different, and the population of Wuyanling had the maximum content of total saponins and polysaccharide. (3) The content of active ingredients revealed stability between the years 2012 and 2013, but the content of polysaccharide was significantly different. The content in 2012 was higher than that of 2013. (4) The content of active ingredients reached the peak in autumn, which was the best harvest season. (5) Among different component content detection of nutritional organs, tubers had the maximum content of ethanol-soluble extractives, total saponins and polysaccharide. Leaves also contained higher content of ethanol-soluble extractives and total saponins than roots and stems. All of these provide theoretical basis for plant, harvest and production of H. zhejiangensis, which is an endemic, rare, and endangered medicinal plants.
